It's not much different from ordering in a magazine. At least on Ebay, lets say you decide to do what I did and buy Fools Die for a penny. Usually it's set up through a store, so that helps with credibility. Plus, you can always check user feedback. If they have negative feedback, read why, and don't order from them. Either way, ordering online is fine if you know where to go. I strongly advise you to check out Ebay. I only got ripped off once, it was because I paid for a bumper sticker ("Protected by the Mafia" bumper sticker) with cash. Plus, the store I bought from had tons of negative feedback. Other than that, everything else has been fine.
